From 8220c99f7e08022aca479b9d22b29f89fbde3ea6 Mon Sep 17 00:00:00 2001 From: Knowit Date: Wed, 29 Apr 2026 02:19:00 +0800 Subject: [PATCH] infra: switch dev1 -> gitea git remote to SSH (port 222) Avoids HTTPS-over-lossy-link TCP cwnd issues that pinned the previous push to ~360 KB/s for 10 min on the batch-50 Step 3-4 commit. SSH key generated on dev1 (~/.ssh/id_ed25519), public key posted to gitea via /api/v1/user/keys (title "dev1-guangzhou"), origin URL updated to ssh://git@git.deepknow.site:222/Facere/FacereDataset.git. Also documents the kernel + git side optimizations applied: sysctl net.ipv4.tcp_congestion_control=bbr (was cubic) git config --global http.postBuffer 524288000 (500 MB) Note: gitea git SSH port is 222, not 22 (22 is the host sshd).
